In Reply to: How fast can we get our boiler started? posted by Gary Grimes on March 26, 2002 at 17:42:31:
: I am working with a small oil refinery in the LA area that is installing a cogeneration system. The local air quality agency will not let us fire the cogen system concurrent with our backup boilers. Therefore, if the cogen system trips offline, we need to start up our Cleaver Brooks watertube backup boiler as quickly as possible to minimize problems in the refinery. Some of our people think it will take 3-4 hours to bring the backup boiler up to speed. Is this realistic? Is there any way to get us up in 15 minutes? I have heard that steam coils in the mud drum will help. Thanks for your thoughts.
If there is a surface blow on this boiler off the steam drum & some way of running pipe off the mud drum from the bottom blow you can run this to a steam heat exchanger using a circulating pump for the boiler water & set it up with a thermostat to run around 180-200 degrees & hot-circ. it. That's a really good way to keep it on standby & bring it up quick.
